Not sure how many people are willing to tag spammers, given that:
That's partially why I sped up work on merit. I don't agree with using the trust system for pure spam; that's not what it was designed for.
I don't think anybody on DT is actively doing so after the merit system was rolled out, so I'm not sure exactly what OP is expecting here. If anyone is concerned about shitposting, they need to report those posts. Mods have a pretty good track record of deleting shitposts and at least temp-banning the offenders.
I used to tag shitposters, as did actmyname, but the trust system is a really bad way to deal with them. It's a misuse of it, but at the time the problem was so out of hand that there wasn't anything else to do and something had to be done. That isn't the case today, because of merits. So this thread should probably be locked and OP would be better off just reporting shitposts. As always, I applaud anyone who takes up the fight against these people.
As you suggest, post will lock. I expect reg tag for them, so they can't participate on sign camp. Specially they are make shitpost due to sing camp. So I think if they got red tag then they will not approved for sing camp. On this way we can reduce shit post. That's why I found and post here. If DT are not going to tag then so it's not meaning to post any more about shitpost. I just want to help keep clean this forum. If you still think need to lock this post. I will lock. And I will not find anymore shit post. I expect reply from you.
